ELIOT S. STAPLES, F IRON MOUNTAIN, MISSOURI.

`Annina mAcnmn Application led March 17, l1921. Serial No. 458,035.

To all whom t may concern Be it known that I, Emo'r S. STAPLES, a citizen of the United States of America.

residing at Iron Mountain. in the county 0t- St. Francois and State of Missouri. have invented new and useful Improvements in Adding Machines, of which the following is a specification. reference being had therein to the accompanying drawings.

This invention relates to adding machines,

n machines used b v banks and similar institutions for adding and tabulating computations.

My invention. in its broadest aspects, involves utilizing digit apertures in lieu of characters or symbols and such digit apertures possess certain advantages in connection with an adding machine.V First. it is lpractically impossible to alter digit apertures and consequentlv a record or account :represented by such digit apertures cannot be changed and any tampering with such a record can be easilv detected. This feature alone eliminates lthe lnefarious practice of unscrupulous clerks in surreptitiou'sly changing bank accounts and `Vsimiliar lrecords.YV

Second, the digit apertures `constitutes a matrix or template by which various instrumentalities are actuated and set for either duplicating or carrvingfforward matter for computing or tabulating purposes` and this may be better understood by brietlv considering the results attained by the machine.

By using my adding machineb one. row of 'figures may be'added to another rowA for instance, a balance to a total. One/set of digit apertures may represent the total and these digit apertures may be utilized. for setting Vmechanism Within the machine. prior to operating the same mechanism. to include the balance. so that the grand total will be lthe result fromy the final operation of the machine. such grand total result also being indicated by digit apertures. That is, the

' digit apertures irrespective of the total thev represent. may in a singlev operation. assist the adding machine to take care of a balance when any further computations are to be made bv the machine. and sinceVv this is automatically accomplished. it is obvious that considerable time and labor will be saved compared to an ordinary adding machine.

Mv invention further aims to provide means for making tabulated computations be utilized for producing a readily dis-y cerniblev record. parallel to the digit record, which may be necessary when such record is to be used by` those not familiar with vthe digit apertures. It is in this connection tbatftnhe machine, to be hereinafter described. maiibe equipped with a suitable printing outlit operatable in svmchronism With the punching instrumentality of my machine.

My invention further aims to combine an adding mechanism and a recording mechapism with a selector mechanism for controlmg and the manner of combiningall of these mechanisms permits of the adding and reoording mechanisms being used independent of the selector mechanism. Then again, the

Vselector mechanism is associated with the adding mechanism so that the adding mechanism may be actuated to assist the recording mechanism in taking care of, or carrying forward, tlrewpreviouswrecord in digits. and lay-*having the addingV mechanism operatable independent of the selector mechanism, it is possible to add in additional matter tothe previous record.

Mv invention further aims to provide av machine in which a matrix. as an apertured card, permits of feelers automatically setting'mechanisms in the machine so as to place the machinerin a. predetermined condition preparatory to a recording'performance.

ln. thelahoveorganization, the matrix or template is in the VVform of a card. sheetof paper or material that may 'be readily the operation of the adding mechanism,

punched to produce the digit apertures or apertures of any configuration representing a code, and 1n selecting apertures ofa card in the machine..provision has been made for positioning the apertures so that the different positions will represent difl'elent digits` i or codes, tor instance. numbers or characters.

A person familiar with the working of the ,i

and its relation to the adding mechanism;

keyboard and release mechanisms; feelers and operating means of the selector mechanism; and clearing mechanism for the machine, will be hereinafter separately and specifically described in detail and operation. together with the novel arrangement and objects accomplished by the combinations of such devices and instrumentalities.

Fig. 17 is a plan of a portion of the machine, showing the key board and a series of keys to be hereinafter considered when referring to the general operation of the machine.

In describing my invention by aid of the views above referred to, I desire to point out that the same are intended as merely illustrative of an example by which my invention may be put into practice, and I do not care to confine my machine to the precise construction and arrangement of parts, other than defined by the appended claims.

The general idea as to the length, height and breadth of the machine may be had by considering Figs. 1, 6 and 7 the latter ligure being practically a continuation of the upper portion of Fig. 1. In the lower portion of the machine the adding selective` clearing and other mechanisms are located with the key board at the front part of the machine and the various operating levers at the right hand side thereof, while in the upper portion of the machine there is the tabulating mechanism and a portion of the tabulating mechanism overhangs a portion of the base of the-machine, providing a throat in which a card or sheet of paper may be placed and shifted from time to time so as to be operated u on by the machine.

From Figs, 1, 6 and-g it will be gathered that the machine body or casing may have extensions in different directions to accom modate a printing outfit, a card cabinet, an index system or ap urtenances that will contribute to the usefu ness ofthe machine; furthermore, the machine body or casing may represent a portion of some other machine.

Furthermore, with the operating cranks of the machine at one side thereof, I desire to suggest that these cranks or their equivalents may be successively operated, in timed relation, from a prime mover or suitable source of power, controlled by the operator of the machine.

The various organizations and machine elements heretofore referred to will be now described under separate captions, and attention directed to those iigures of the drawings best showing each organization.

Cards. (Figs. 2, 10 and 14).

The portion of a card or sheet of paper A shown in Fig. 10, has a side edge thereof provided with positioning notches B so that this card may be correctly positioned in the machine to be punched. Transversely of the card is a series of digit apertures C and each aperture is circular with an inwardly projecting nib or lug D constituting thel digit portion of the aperture according to its location about the circumference of the among other things, two side Walls 1 and il.'

aperture. The inwardly projecting nib isy substantially semi-circular and consequently imparts a somewhat crescent shape to the` meral 5; thirty-six degrees cast ot south thel numeral 4; eighteenl degreesl south of east the numeral 3; eighteen degrees north ot east the numeral 2; and thirty-six degrees east of north, the numeral 1. In other Words. the circular aperture is divided into nib degrees representing nine numerals, characters orl symbols of a code and With the code understood it is possible toA interpret or readthe nib positions shown by the series of digit apertures. lVhen a gap appears in the row of digit apertures it indicates naught or zero as designated in Fig. 10, with numbers 1, 2, 3 0 5 6 0 8-9 indicated by the digit apertures and such digits may represent a large number or dollars and cents, 'for instance $1,230,56tl.89.4 i. l

. Assuming that $5,346,572-31 isvto be added to the first sum of money, the card A is provided with another series of digit apertures E which are disposed in a transverse row contiguous to the first row of digit apertures Trhe same punches employedfor producing the' digit apertures C are employed for producing the digit apertures E but the punches are partially rotated so that the nibs appearing in the digit apertures E will t indicating the sum 'ot $657 7 ,13320, this being the totalpof the two have positions sums of money mentioned above. It is only necessary to compare the vtwo rows of digit apertures to note that the nib position representing a number in one row corresponds to the nib position of the samenumber-inthe otherrow.. l f f .f

With the-'card or sheet of paper A made of nib D may be utilized for lactuating purposes, and I here direct attention to the fact that it is practically impossible to'alter the digit apertures for misleading purposes.

Machine Body/ (Figs." 1, 3, et, 6, 7, 8, 11

and 17). f

The machine body or casing includes,

an intermediate longitudinal partition 3,

a front wall 4,'provided with a wall extension 5, a top wall or table 6 having an in- For instance, as indicated in clined portion 7 on the wall extension 5, and the side walls 1 and 2 have the upper -iront edges thereof extended to` meet the Wall extension 5 so as to provide an inclosure overhanging the front portion of the machine. The partition and walls thus far described provide the main compartments of the machine and above the top wall or table 6 is a tabulating compartment composed of side walls 8 and 9,'a bottom wall 10, a front wall 11, a top wall 12, a rear wall 13, a horizontal partition 14, and "a vertical longitudina-l'partition 15 connectin the bottom wall l() to thev horizontal partition 14.. By

vreference to Figs. Gand 7 it will be noted that the bottom wall 1,0 of the tabulating compartment is in spaced relation to the.

front wall or table 6 thereby providing a throat in which the card or sheet of paper A may be placed to be operated upon while in the machine.

The inclined portion 7 of the topwalLor table 6 has longitudinallyA disposed key slots 16. yand further back inthe top wall or1 table 6 are feeler openings or a slot 17 vertically alining with' the feeler openings 1S,` in -a transversely -disposed feeler guide 19 mounted on the top Wall 6, said eeler guide being in spaced relation to thetop wall and having its front edge curved upwardly so that the card Amay be easily placed under the eeler guide.

To correctly position the card A with the digit apertures() in vertical alinement with the eeler openings 18 and 17,'a longitudinaL ly disposed guide 20 is mounted on the front wa-ll 6 and providedavith a lug or projecs.

tion 21 (Figs. 1 and 17) adapted to engage in one o the notches B of the card A, the notches being spaced for a predetermined distance between the .transverse digit apertures in the card.

` Adjacent ,the front upturned edge of the rows of v feeler guide19 is a countersunk transversely disposed pad or cushion member Q2 which is suitably held within thetop wall 6 beneath a series of punches,` operatable from theupper portion of the machine, said pad im) n preventing injury to 'the cutting edges of the punches. which yare adapted to produce the row of digit ap'erturesvC.

to re-set the rack bars24 after each actuation. The ends of the rack bars \are connected to cables or flexible members 51 trained over sheaves 52`suita`bly supported from the front wall 11 and the rear wall 13, asbest shown in Fig. 8. The cables or flexible members 51 extend downwardly through the top wall or table 6 and are attached to .drums 54 rotatably supported about one end of a shaft 58 which is suitably fixed within suitable bearingsof the side walls 1 and 2.- The. cables 51 are attached to the drums l54 so -as to kbe wound thereon and the drums are disposedv in parallelism with hollow hub portions .55 thereof telescoping one another 'on'gthe stationary l shaft 53.- On account of'arrangementthe drums 52 havefhubsswhich Vary in diameter andthe arrangement oit the yhubs L55 affords 'a substantia-libearing-jforv the,`

.` Loose on the stationary shaft Q53; .are vparallelv closely assembled gear wheels 5 6 aving side rims 57 .(Fig. 7) and hollow i hubs 58 with the hubs extending in an o pposite direction from theside rims 57. The

hubs 58 telescope one another, similar to the' hubs of the drums.54 and the hubs 58'are .suitably coupled to thehubs 55 of the drums 54, for instance, as zit-59,3 such. connection permitting'of the drums and gear wheels eing easily, quickly and properly assembled aboutthe stationary shaft 53,'so that a rear wheel is coupled to a drum to be operated .in

Y unison therewith. As best shown in Fig. 6 the adjacent gear wheels, said side'rims will a' 4 drums 54 are assembled at'one end of the sta# tionary shaft 53 and the gear 5 wheels 56 at the opposite end of said shaft, and with the side rimsof the' gear wheels abuttin ford bearings for adding rings60 andseg# ment gears 61, there being an adding ring and a segment gear associated with each of" the gears 56,and the adding rings are sand?.

wicliedvbetween the segment gears 61- "andthe gears 56. The adding rings -60 are pinned or otherwise xed to the side rims ot the gears 56, as at 62, and each adding ring has a beveled tooth 63, asshown -in Figs. 7 and 9. Each segment gear 61 has a stop ,lug `64 diametrically opposite the toothed portion and the stop lug 64 is adapted to engage a dependingstop 65 carried by the top wall or table 6. The stop lug 64 is also adapted to engage ka radially disposed stop pin 66, on the side rim 57, said stop pin being in the path of the stop lug 64, as shown by full lines in Fig. 7 and by dotted lines in Fig. 16. As a result of this arrangement the segment gear 61 may be partially rotated, in a counter-clockwise direction, to cause the stop lug 64 thereof to impinge against the stop pin'66`and'impartn1oive- .Y

Before considering the' adding feature of' my machine, it is thought best to brielly re- 'hearse they mechanism actuated by the gears 56. vSincethe machine'has been designed for producing nine digit apertures inthe card "A, there must necessarily be nine punchesjnine rack .bars fof rotating the punches, nine drums for Athe yflexible mem-- bers, and'nine of the ,gezetrjt'lieelsy 56 with soi an addingjringand segment gearA associated with-eachv of the vgear wheels156.`f So,

linorderthatthe adding feature may beap.-

plicable' tov each :of -thefgear wheels 56, an adding mechanism is locatedladjacent .each

A jgear wheel( f Mounted in the side wallsvliand l2 and' eX- A tending transverselyotthemachine are rods' 67', 68, 69and70, and slidable on the Arnd-.

68 and having a. slottedeonnection with. the

4 rod 69 are tiltable' arms-..71-corresponding in number to. the'addinfrings 60. The 'i tiltable arms 7 1ere-space a art ontheredg l .68 'by spacers k72 Zand each `tl-ltable arm has adding' ring 60. I Pivoted on the rod ,ward ends" of the levers 74 are' connected ja beveledy tooth ..73-adapted-`tojbe engaged fand lelevated by the beyeledtooth Gant-the A andjextendingener I I. g the tiltable arms 71 are 'levers 74. .'1h'e.for"'` arms 7l, and whenthe'tiltable arm is ele` Y' yated bythe beyeledftooth 63 et an adding ring 60,' the rear end 'et the tiltable arm elevates the forward endfof thelevier 474,

. againstv the action of the .spring 75', causing Y .the lrear endet the lever 74f'to"bejlowered. This'V may be best` understoodt'by reference to Fig. 9, where the purpose ofthe tiltable "1 ed lon the rear end of thev lever 74 is a'pawl' 5le`ve1's'74 `maybe further understood; Pivot v-76 having its upper end connected the end of the lever' 74 by a/coiled retractile spring les l77, and theretractile force 'ofthis spring '1 maintains a'stop .78 of the pawl normally in engagement with the lever 74,'so thatthe vlower'end of the'pawl 76/ is in '4 engage one of the gears 56 when 4 lowered. When one of'thetiltable arms 71 is tilted it is restored to normalposition by the retractile force of a coiled spring 79 connecting the tiltable arm'to a rod SOextend-4 ing transversely of the machinei and supported by the'side walls 1 and 2.

Connecting the side walls 1 and 2 of the' machine body and extending ,transversely thereof in proximity to thejgearwheels 56 is another rod 81, and pivoted on said rod are detents 82 normally engaging the gear wheels 56 to hold said gear wheels in ad- /po'sition to f the pawl is' Fulcrumed on the ends of the stationary shaft .53 are bell cranks 84 `having arms thereof connected by transverse rods 85 and 86, the rod 86 being 'normally under portions of the pivoteddetent 82, as shown in F ig. .9.so that the rod 86 may, upon actuamecktion of the bell cranks 84, shift the detents 82 out of engagement with the gear wheels 56, thereby permitting said gearv wheels to assume normal position.

Rotatable on the rod 85 are pinions 87 meshing with the gear wheels 56 and pinions 88 meshing with the segment gears 6'1, and

these pinions loosely ride in engagement with the gear Wheels 56 and the segment gears 61 when the bell cranks 84-are actuated to clear the machine. i A i To maintainthe pinions 87 and 88 in'op'-,

erative relation to the gearwheels '56an`d-y segment gear wheels 61, the bell cranks 84 have stop lugs 89 engagin studs 90 on the walls 1 and 2," and said be l cranks yare connected lto the walls' by coiled retractile springs 91. y

Since the gear wheels 56 are located at one end of the stationary sha-ft 53 and the partition 3 cut away, as at 92,`to provide clearance for the adding and power trans-- mission mechanism, it is only necessary to locate the actuators between the wall 1 and the partition 3. Connecting the wall land the partition 3 are transverse rods 93 and 94 and slidable on these rods in a horizontal plane are, actuator racks 96 for the pinions lill 87 of the gear wheels 56 and actuator racks 95 for'thepinions 88 of the segment gear 61, said'a'ctuator racks being slotted, as at 97, to provide clearance for the rods 93 and 94. The actuator racks 95 are of a rather l peculiar shape by vhaving the rear ends thereof terminating in stepped or notched heads 98 and spring supporting rods 99.y The rear ends of the actuator racks 95 rest on a fixed transverse support 100 connecting the wall 1 and the partition 3, and adjacent this support, the rear ends of the actuator racks 95 have stop lugs 101, the purpose of which will hereinafter appear.

The spring supporting rods 99 of the actuator racks 95 extend through a depending support 102 of the top wall or table 6,

and on said supporting rods are coiled expansion springs 103 en aging abutments 104a of said rods, so'that t ie expansive force of the springs 103 may constantly tend to pull the actuator racks 95 rearwardly.

The actuator racks 96 have the forward ends thereof enlarged to provide keepers 104, depending apertured lugs 105, and laterally extending stops 106. The depending apertured lugs 105 are 'connected by coiled retractile springs 107 to a transverse 'rod 108 connecting the Wall land the partition 3. The purpose of the keepers 104 and stops 106 will appear in connection with the key board and releasing `mechanism to be hereinafter described;

Selector mechanism amd its relazfz'cn to the adding mechanism. (Figs. 1, 3, 6 and 7).

The spring supporting rods' 99 of the actuator racks extend through a transverse slotted guide member 109 supported from the lower face of the top wall or table 0, and thisslotted guide member is in proX- imity to the stepped heads 98-of the actuator racks 95 with the slots in said guide member of sufcient'depth to' the stepped heads 98. i

Slidable in theslots ofthe guide member 109, are two-partselectormembers 110 which.

confrontthe stepped-heads 98 and these selector members are vada ted to be vertically reciprocated'in the 'ui e member 109 and' positioned" 'to provi e abutments and sto the rearward movement of the stepped head1;

98,' thus limiting the rearward movement of the actuator racks 95. y'Byreference to 1 Fig. 1, it will be noted that the stepped heads havev stepped portions or shoulders corres ponding innumber to the punches of the 'tabulating mechanism and the digit apernnA provide yclearance for tures C to'be produced thereby, and by the selector members 110 limitino the rearward movement of the actuator ractks- 95, the rotation of the gears 61 is predetermined, and consequently the rotation of the punch shafts 26.

Pivotally connected to the rear ends of the slidable selector members 110 are hangers 111 and pivotally connected to said hangers and disposed practically in parallelism are fulcrumed levers 112 extendin througlislots of the guide member 109. rllhe levers '11:2

are fulcrulned on transverse rods 113 con:l

necting the walll and the partition 3. These levers will again be referred to when considering the feelers and the operating means for the selector members. Key board and releasing mechanism. (Figs.

f 1, 8, 5 and 17).

The partition 3 terminates at the front wall 4 of the machine body, without eri-- tending into the forward overhanging portion of said machine body, and connecting the side walls 1 and 2 1s a transverse connectedby coiled retractile springs 119 x 113 may be held in lowered 1o a depending iinger 117 adapted to be placed i '4 *wall 1 and -j l 127 to a transverse bracket 121 and t-he rod' 114. Pivoted on this rod are a series ofkey members 115 having vertical extensions prajecting through the key slots 16 in the inclined portionj7 of the top wall or table 6, and each key member has a numbered or designated head or linger piece :116, as best shown in Fig. 17. Each key slot provides clearance for ten key members so that' there are ninety key members for the key board, and each key member has inthe path of the stops 106 of the actuatorl racks 96. The forward end of each key member 116 has a rearwardly extending arm 118, and these key member arms are to a transverse rod 120 supported bythe 121 of. the partition 3. The retractile force vof the springs 119 hold lthe arms 118 normal- -1 ly elevated* against a v.connecting the walls 1 and 2 of the machine body, and consequently the key members 115 are maintained normally elevated ready to he'depressed. j

The `forward ends of the latches 126 are connected by coiled retractile ysprings rod 128 connecting the side wall 1 of the machine-body. y

Rotatably supported by the side Walls 1 and 2 'is a cam shaft 129 which has one end thereof projecting through the side wall 2 and provided with an operating crank-130.

Jqi'iallyspaced about the periphery of the 'camshaft 129 are cams 131 corresponding in number to the latches 126 and when the cam shaft 129 is rotated the cams 131 are. adapted toy depress the forward ends of the latches 126 and cause the rear ends-of said latches to release the keepers 1.04 ofthe i actuator racks Y96, so that said actuator racks ma move rearwardly, under the influence o the springs 107, and actuate the pinions 87 and the gear wheels 56.

With the latch bar 154 and the stop lugs 101 beveled, as shown in Fig. 1. the actuator racks 95 may be shifted under said latch bar with said latch bar snapping behind the stop lugs 101 to hold the actuator racks 95 -iii' retracted positions. l-

The feeler shafts 137 vertically. aline with l the openings 17 in the top wall or table 6,

and the upper end-oteacliieeler shaft has a cylindrical teeler 158, best shown in Fig. 14e. The upper end of the feeler `-158 terminates in a nosev159'so that it may readily enter one ot the digit apertures C, and the cylindrical body of saidl feeler has a spiral way or cam surface 160 with its lower end communicating with alongitudinal groove 161. With the feeler entering the'digit opening C thespiral `Way-160receives the nib D and said` nib" bears against the walls of the spiral way 160`antd causesthe feeler 158 to "21e rotated until the nib. enters the upper end of the groove 161'When 'said feeler ceases t0 rotate but may move verticallyv in the digit aperture C. f

W hen the eeler shafts 137 are raised by the yoke 139, the rectangular portions 136 oi: said shafts slide through -thewvorm's 133v until, the feelers 158 start to revolve, when :movement is imparted to the Worms 133 and' as these'ivorms operate inthe stationary-supf. port 132 the cages 134 will `lie-elevated Yto, actuatejthe selector members.110.Y As'the` Worms 133" aredriven bythe feele'r Vshafts .137 the upper ends of the Worms shift away from the supports 132,." and in .order that the Worms' will'always be correctly posi.- tioned, relative to` supports 132 and thus cause the feelers 158tobe correctly positioned relative to digit apertures'the upper end of each worm 133 has la radially disy posed pin 179 adapted to ride intov and out of engagement with a stationarypin 180011 the support 132. The pins 179 and 180 Will insure each feeler head 158 being correctly positioned Jfor the upper lend of the inclined Way or cam surface 160 to impinge against the nib D of the card A. The inclined Way or cam surface 160 has been developed in Fig. 2 of the drawing, and by reference thereto it Will be noted that such spiral inclined Way is opened so that as `the teelers vertically before being rotated than those feelers representing the numerals 7, 8 and 9.

-In consequence of this arrangement ot' the open inclined ways 160, the ,feelers receive different degrees of rotation'and "after 'the feeler has been properlyr adjusted'its. vertical movement is permitted by reason of the vertical 4@groove 161.' The distance between the lower ends of the shoes 153 and the upper ends of the shoes 140 is a little,y greater than the vertical dimension of thetfeeler slopes or Ways, so that While the grooves 161 of the eelers are passing through ydigit openings. the shoes 140 may raise theshoes 153 and the latch bar 154.

Clearing mechanism' for the machina (Figs. 1, 3,7 and 9).

The bell cranks S4: have been described as pivoted on the shaft 53 'with' the 'rod S6 extending under the detente 82m shift said detents and release theg'earsfso that the ,gears 'andelements actuated directly or indirectly thereby may be restored to normal position. In order vthat the bell cranks may be actuated, oneI of the bell cranks 84 has a .handlex1'62 protrudingthrough'- an. openingyprovided therefor, in'

the top wall or' table 6A of" the machine.

This handle may bepushed ,rearwardly tol shift the detentsr82, 'and said handle also constitutes a part of the clearing mechanism forsuch key members as has been depressed and set7 with the'dogs 123 holding the ar1ns"11 8. i

is' a reach rod 168 and the` lower ends 'of the reach rods arepivotally connected to cranks 164 on the ends of a., rock shaft 165 -journaled inthe sidewalls land 2 or bearings carried thereby. On the rock shaft 165 is a long ccm member 166 which may be swung against the dogs 123 to shift the dogs out of engagement with the arms 115, thereby permitting the retractile force of the springs 119 to restore the key mem-Y its bers 115, to normal elevated position. The

cam member 166 is adapted to ride into depressions 167 of thel dogs 123 and temporarily hold said dogs stressed While the key members 115 areact'uated by the springs 119, also While other parts of the machine are being cleared.

General operai/ima I From time to time theoperationof 'certain organizations of the machlne have been de.-

scribed, andV with the machine. cleared, I` lwill 'now assume that `the card A has previ-y ously receivedfthe digit apertures D representing the sum Aof 81,230,56089, as re resented by the top row of apertures in ig. 10 of the drawing. f

The card A is placed under the feeler guide 19V with the notch li3, opposite` the row of apertures C, receiving the positioning member or lug 21 of theguide 20. Then the digit aperture C will be in Vvertical alinement with the feeler openings 17 and 18 to permit of the feelers 158 moving upwardly` through the table, the-apertures C and the feeler openings 18 of the guide 19; it being understood that the bottom wall 10 of the tabulating mechanism is located a suflicient operation lhaving been pers 123 whichhave been prep` I "the arm. the shaft 175,

the present instancethere distance above the top -wall or table 6 to provide clearanceffor 'the upwardV movement of the feel-ers 158. The bottom wall 10 may f Ube 'slottedl orl 'apertured to permit" of theV feelers entering the tabulator compartment just so the feelers do notstrik'efthe lowermost rack bars 2 1-therein.V Togindicate such distances and permit of various parts being shown in the drawings as'large as possible, the various views have been broken away.

Asthe other selec-j shoulders 'ofthe-'heads 98 are tor! members have 'been a'dusted'in the positions, and, figuratively speaking, represent the numerals 1, 2, 3,5, 6, 8, and 9 such shoulders-so designated on Fig. 1 engaging As the released actuator racks 95 move rearwardly said racks impartl movement toA the pinions 88 .meshingk with. thefsegment tated,-each a prescribed number of degrees.

The partial rotation ofthe segment gears 61 is transmitted to the drums 54 by virtue of` the hub portions y58 and 55, and the drums 54 pull on the cables 51 and shift the rack bars 24 against the action of the springs 49, Thev rack bars 24 meshing with the pinions 25 cause the punch shafts l26 to berotated e remainingv im'pinge against selector' members 'v Since gtwgo' 'of lthe 'selector Amembers and position the punch members 28 in accordance'witli the digit apertures of the card A. lf the positioned punches were to bc for the time being.

The next operation is that of punching or depressing the finger ieces 116 of the key members 1,15 in accor( ance with they sum to be added, which according to the present example., is $5,346,572-31. In operating the key board, the longitudinal rows of keys are successively used, the keys one, three, two,

seven, five, six, four., three, five, being suo-I cessively punched in their order and as the key members 115 are depressed the arms 11S,

of said key members are engaged and held by the dogs 123, thus placing the fingers 117 of the key members 115 in the path of the stops 106 of the actuator racks 96.

The next operation is that of rotating the -cam shaft 129. so that cams 131 thereof will elevate the latches 126 and release the actuator racks 96. These actuator racks are shifted rearwardly, under the infiuence of the springs 107, until the -sto s 106 of sald racks abut the fingers 117, t e position of said fingers defining the movement of the racks 96. The racks, however, have shifted sufiiciently to operate the inions 87 of the gears 56 and said gears wi l transmit power to the rack bars 24, so that said rackbars may further rotate the adjusted punch shafts 26.

The first punch shaft at the right hand side of Fig. 6, having been adjusted to take care of the nine cents, represented b the first digit aperture, at the right han side of the card A, must be further adjusted to include the one cent to be added thereto, and this means that the first punch shaft must be rendered inactive to leave a blank space (in the card representing naught, and that one must be carried to the next column and added in with eight plus three.

The segment gear 611 having`v been actuated to take'care of the nine by the Vselector mechanism, depression of the kcy one causes the gear 56 to he further rotated and. the first punch shaft is actuated to place the tooth in vertical alinement with the notch 4:7 in the tubular guide 34 associated with said unch shaft, conse uently when the cross ead 35 is lowered, 1t will not depress the first punch shaft but allow it to remain dormant, so that no aperture is punched in the car A. This leaves the blank space on the card indicating naught.

One must, however, be carried into the next column and the second punch shaft, from the right in Fig. 6, is further adjusted to take care of the one. This has been accomplished bv the pinned adding ring of the previously rotated gear 56 haring had its beveled tooth 63 brought Aover is accomplished by the tiltable arm 271, lever 74, pawl 76 and gears 56, just as in the first column. It is thought unnecessary to rehearse the entire setting of the punch shafts 26 for the complete sum of 255,346,57281, in addition to the original setting of the punch shafts, land as soon as the punches have been properly set the crank 43 is operated to lower the cross head 35 and cause the tubular guides 34 thereoil to depress the punch shafts 26. As the punch members 28 encounter the card A the second row of digit apertures C are pro' duced, representing the sum of $6,577,- 13320, and the material removed from the digit apertures is eventually ejected from thepunch members 28 by the ejectors 30.

I an further sums are to be added to the tota ,the card A is advanced on the table 6 so that the feelers may enter the digit apertures E,- but before the selector mechamsm is placed in operation, the machine is cleared to permit of the various mechanisms assuming normal position.
